MECHANICAL AND MAGNETIC TOY.

Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed February 27, 1900. Serial No. 6.700.

To .cr/ZZ whom it may concern:

Beit known that I, HERBERT COTTRELL, of the city of Newark, county of Essex, State of New Jersey, have invented certain Improvements in Mechanical and Magnetic Toys, of which the following is a specification.

My invention consists in producing a novel mechanical and magnetic device in which by means of alternate magnetic attraction and repulsion various figures and apparatus placed upon top of the toy may be caused to seesaw or to rotate (Waltz) or to perform eccentric movements. To do this, I provide a suitable frame to hold one or more magnets, placed, preferably, in a horizontal position upon the top of the frame. I also provide a v balance-wheel, fixed upon a spindle of steel made permanently magnetic, placed, preferably, in a vertical position and-adapted to rotate a table provided with a circular rim of iron wire bymeans of the attractive contact of the magnetic spindle therewith. I also provide separate permanent magnets of both straight and horseshoe form, mounted upon suitable movable supports, which may be placed upon the table and be caused to move in various ways when the mechanism is in motion by means of magnetic attraction and repulsion. These movable magnets may have paper or other figures mounted thereon and make an attractive or amusing display.

Referring to the accompanying drawings, which form part of this specification, Figure l is a vertical section in which the main features of my mechanical and magnetic device is shown. Fig. 2 is a plan of the same. Fig. 3 shows a horseshoe-magnet pivoted upon a movable support and is adapted to rotate and reverse when in action upon the table. Fig. 4 shows a straight magnet pivoted upon a movable support and adapted to seesaw when in use. Fig. 5 shows a straight magnet attached to a slightly-convexed plate and is adapted to perform eccentric movements when used as described.

Throughout the drawings similar letters of reference refer to similar parts.

Referring to Fig. 1, the operation is as follows: The balance-wheel i, mounted upon a magnetized shaft h, may be caused to spin upon point k in recess in plate b and is held vertically in ournal ,fitted loosely in plate a, which plate is of non-magnetic material. A circular plate f is mounted upon shaft e, pivoted at n, plate b, and loosely held by plate al and kept in place by collar o. Said plate f is of non-magnetic material and is centrally swaged to receive head m of shaft e. It is also preferably fiat on top with edges turned, as at l, to hold an iron wire g. This iron wire is attracted by magnetized shaft 7L, and as 7L, carrying balance-wheel i, spins the attraction between shaft 7L and iron wire rim of plate f causes plate f to rotate. By this means friction is reduced to the minimum, and a slight impulse keeps the toy in motion a long time. In a space between plates a and f magnets d d are held. (Shown as to position in Fig. 2.) These magnets d d are placed, preferably, parallel, with opposite poles opposed; but other positions and other form of magnets may be used without departing from my invention. The poles of the magnets are placed so far apart as not to cause figures or apparatus placed on top of the toy to tend to cling to or follow them, but only to act by intermittent attraction and repulsion, so that the device shown at Fig. 4, for instance, may be caused to seesaw when placed at any point on top of the toy. Little paper figures may be mounted upon the magnet o of Fig. 4 and make an attractive display. Fig. 3 shows another form of magnet s, mounted so as to turn loosely upon point u, held in base t. When this device is placed on top of toy when spinning, the attraction and repulsion of the magnets give it a waltzing or turning motion, so that any odd or pleasing figure may be attached thereto and make an interesting eX- hibit. Fig. 5 consists of an oblong or buttonshaped plate y, carrying magnet z. Its lower surface is slightly bulged, so that it may turn freely, and this may carry amusing figures and be operated like the foregoing. These specified devices are onlygiven as instances of what may be employed. The range of apparatus operated by this toy may be eX- tended indefinitely.

It is obvious that the plate f might be placed below the plate a within the structure and may be used to carry and rotate magnets d d and that the seesaws, &c., could then be operated upon plate a without departing from my invention.

Having thus described my mechanical and magnetic toy and given instances of its operation of devices, what I claim, and desire to secure by Letters Patent, is-

1. A mechanical and magnetic toy, comprising a frame, a central spindle having bearings in said frame, and carrying a nonmagnetic table-plate having an iron rim upon IOO IIO

its periphery, a magnetic shaft having a balance-Wheel fixed thereon, and having its upper end in Contact With the iron rim, bearings in the frame for the said magnetized shaft, a

ble-plate may be alternately attracted and repelled by the said magnet or magnets, substantially as described.

3. A mechanical and magnetic toy7 comprising'a rotatable non-magnetic table or carrier, having an iron'peripheral rim 5 a rotatable magnetized shaft heldin a frame in bearings, and having a balance-Wheel fixed thereon; the said iron peripheral rim arranged in contact with the said magnetized shaft to ladapt it to be rotated by magnetic attraction,

substantially as described.
